Note this is a single unstacked 30 frame despite the info on the image

I've now removed the 10mm spacer so the distance from the reducer to the front of the Lodestar is now 53mm - this gives a focal reduction of about F3.5 and much lower distortion.

I will continue to experiment with the spacing but am happy with the results:

Note this spacing will result in severe coma - I'm still experimenting with the spacing.

This was taken with Lodestar-C, F3.3 reducer and 102MAK using Lodestar Live and 35nm Ha filter.

Hi

You do not need the flip mirror - it just makes getting a target on the screen easier and you can flip between visual and video.

The length of the T extension between the flip mirror and the fine focuser will vary depending upon whether or not you have a focal reducer fitted to the nosepiece of the camera (shorter with no reducer).
